KNIFE-CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 362,261, dated May3,1887.

Application filed June 8, 1886. Serial No. 204,445

To all whom, it may concern.-

Be itknown that W6,THOMAS SYDNEY EVANS and FRANKLIN ROBERT J ACKES, bothof Winnipeg, in the Province of Manitoba and D0- minion of Canada, haveinvented a new and Improved Knife-Cleaning Machine, of which thefollowing is a full, clear, and exact description.

Our invention relates to machines for cleaning knives, and has for itsobject the production of a machine that, while cheap and simple inconstruction, is reliable and efficient in operation.

It consists in concentrically-arranged cylinders having an annular spacebetween, to whose opposite surfaces are affixed a series ofspirally-arranged cleaners, the lower series the reverse of the upper,adapted to revolve in an outer cylindrical casing, and also in detailsof construction ofthe cylinder and casing, as will be hereinafter fullydescribed and claimed. I

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective View of our knifecleaning machine; Fig. 2, alongitudinal section thereof; Fig. 3, a Vertical section taken throughline a: w of Fig. 2; and Fig. 4 a plan View of the inner cylinder,illustrating the spiral arrangement of the cleaners thereon.

A is a cylindrical casing provided with heads B B, andsupported uponsuitable standards, G G.

O G are metal cylinders concentrically arranged, forming an annularspace between. WVithin the space thus formed are two series of cleaners,a a, of leather or other suitable material, secured to the cylinders O Gby metal binding-strips b I). These cleaners a a. are arranged spirallyat proper intervals, the one series to cover the inner surface of thecylinder 0 and the other the outer surface of the cylinder 0, extendingthe full length of the cylinders, as shown in Fig. 4..

The spiral arrangement of the cleaners a on the outer surface of thecylinder 0 is the reverse of that around the inner surface of thecylinder 0, forming thereby a series of reverse spiral laps, as shown inFig. 2.

(No molcl.)

The cylinder 0 is made secure to the head a of the cylinder 0 at oneend, the other end being fastened to the shaft D by a suitable plate, d,and by means of the crank E upon the end of the shaft D, which passesthrough the machine from side to side to bearings in the standards G G,the two concentric cylinders, secured to the shaft D, as above, arerevolved as one cylinder. A guide-ring, 0, made preferably of leather,is fastened to the end of the cylinder 0, around the plate (I of'theshaft D, and extends up around the cylinder 0 to a line with the topedges of its cleaner a, and serves to guide the knives when insertedthrough openings 9', hereinafter described, between the upper and lowerseries of cleaners.

A springpawl, 71., secured to the under upper side of the casing A, isadapted to engage notches s in a flange formed upon the head 0 of theouter cylinder, 0, to prevent the cylinders from being turned in thewrong direc tion.

Between the cylinder 0 and the casing A is an annular space, H, intowhich the cleaning compound is poured, through a screw-capped opening inthe top of the casing.

Openings k k are made at intervals in the top or outer surface of thecylinder 0, to admit the cleaning compound to the leather cleaners act,as it is gathered up by the metal cleats or conductors ii, fastenedimmediately over them. These cleats or conductors are formed of a flatpiece of metal, having ashort arm bent over and fastened to thecylinder, as shown in Fig. 3.

In the head 13 of the casing A slots 1* are cut in a right line with thejunction of the leather cleaners a a, through which the knives areinserted to be cleaned. Each slot is provided with a semicircular guide,9. (Shown in Fig.1.)

The fact of the leather cleaners being fastened to metal cylinders bymetal cleats, as shown, prevents the possibility of any expan sion orcontraction.

In the operation ofonr knife cleaner a number of knife-blades areinserted through slots cut for that purpose in one end of thecylindrical casing, as shown in Fig. 1. The knifeblades thus insertedare guided by the leather guide-ring o to a contact with and between thereverse spiral leather cleaners a a of the cyl- ICO inders C G, asillustrated in Fig. 3. A cleaning compound is poured into the annularspace.

H, between the casing and the cylinder 0, through the capped opening inthe top of the cylinder. The cylinder is then set in motion by turningthe crank E, and cleats or conductors z z upon the outer or upper sideof the cylinder G gather the compound and convey it to the spiralleather cleaners through openings 7c, formed in the cylinder 0immediately under the cleats or conductors t i. As the knife-bladesremain stationary and the cylinders are revolved, they are rapidly andthoroughly cleaned through continued contact with the series of reversespiral laps of the leather cleaners well covered with the compoundconveyed to them, as above.

Having thus described our invention, what we claim as new, and desire tosecure by Let ters Patent, is-

1. In a knife-cleaning machine, two concentrically-arranged cylinderscarrying upon their opposing surfaces spirallyarranged cleaners,substantially as shown and described, and for the purpose herein setforth.

2. In a knife-cleaning machine, two c0ncen-.

trically-arranged cylinders adapted to revolve together in aninclosing-casing, carrying upon their opposing surfaces spirallyarranged cleaners, the spirals upon.the two cylinders being reverselyarranged, substantially as and for the purposes herein set forth.

3. In a knife-cleaning machine, the combination, with two concentriccylinders adapted for revolution about a common axis, of metal clampsspirally arranged upon the opposing guiding-disk interposed between theends of 5 said cylinders and the knife-holding disk, substantially asshown and described, and for the purpose herein set forth.

5. In a knife-cleaning machine, the combination, with the metal cylinderC, provided upon its outer surfaces with opening is and cleats orconductors i, and upon its inner surface with spirally-arrangedcleaners, of an inner cylinder, 0, concentric therewith and attachedthereto, the cylinder C having cleaners spirally arranged in an oppositedirection to those on the cylinder 0, the two cylinders being mountedupon a shaft, D, and adapted for rotation in a casing, substantially asshown and described, and for the purposes set forth.

6. In a machine for cleaning knives, the combination, with the casin gA, fitted with ascrewcapped central opening and a spring-pawl, h, of theflanged head 0 of the cleaning-cylinders, provided with notches S,adapted to receive the pawl h, substantially as shown and described, andfor the purposes set forth.
